TL;DR: In this article, a controlled experiment was implemented using 60 participants who copied the shape of a 3D "target handaxe form" from a standardized foam block, and 30 participants were shown manufacturing techniques employed in the production of the target form and the target forms itself.

TL;DR: In this article, shape data were generated and statistically analyzed under controlled and replicable conditions and participants were required to copy the shape of a target form as accurately as possible using a standardized block of plasticine and a steel table knife.

TL;DR: It is outlined how a “quantitative genetic” framework to these issues provides an essential means of linking these inherent micro- and macro-evolutionary factors into a coherent whole, while also simultaneously reconciling the potential influence of different sources of variation that are part of a temporally and geographically dispersed entity such as the Acheulean.

TL;DR: It is concluded that, although high fidelity transmission is likely to be implicated in cumulative culture, action copying is not always necessary for this to occur and the stark absence of unequivocal examples of cumulative culture in nonhumans may be attributable to factors other than imitative ability.

TL;DR: In this article, the relationship between behavioral variability and artifactual variability is studied empirically from an explicitly "microevolutionary" perspective, where the authors experimentally simulated artifactual variation in two populations of manufacturers, involving only a single behavioral difference in terms of their "tradition" of manufacturing tool.
